To aiwhom it may concern:

Be it known. that I, CHARLES B. Kmtnja citizen of the United States,residingat Detroit, county of Wayne, State of Michigan, have in ventedacertain new and useful 1m provelnent in Gas-Engines, and declare thefollowing to he a full, clear, and exact description of the same, suchas will enable others skilled in the art to which it pertains to makeand use the same, reference bein had ,to the accompanying drawings, whicform apart of .this specification.

My invention relates to gas engines and i an object of my improvementsis to provide an improved .gas engine for useupon automobiles. Iaccomplish this result in the device illustrated in the accompanyingdrawings, in which I Figure 1 is a side view, partly broken away, of agas engine embodying my invention. Fig. 2 is a front view of the same,partly broken away. Fig. 3 is a section on the lines 33 of Fig. 1. Fig.4 is a detail view of parts forming the means of securing the tan inposition. These parts are separated in this view, and mostly shown insection.

In the drawings similar letters refer to similar parts.

A, A represent the casting in which are a plurality of verticalcylinders for a gas engine.

B is the common crank-case.

G is a casing formed integral with the casting. A, A, except; theremovable front plate forming a cover for the casing.

E is a carbureter.

t. is a forked intake pipe.

D is a pipe leading from the pipe G to the carbureter E.

e is a throttle valve.

F is a pipe leading from the carbureter E to the casing G. The valvestems and rods 1 and s rings H therefor are-inclosed in the casing gindicates perforations in the forward end of the casin G.

H indicates the springs upon the valve, and l the valve operating rods.

J, J, J, indicate the exhaust valves.

K is a hollow column extending upward and forward from one end of thecrank case B, its interior communicating at its lower end with saidcrank case and at its upper end being open to the outer air.

Specification of Letters Patent. Patg ntedJan. 23, 19 3 Applicationfiled November 1 1910. serial No. 590,142.

I. L is a perforated diaphragm in the column K. v

M is a compression spring, one end of which rests upon thediaphragm L.

N is a sliding crosshead adapted to fit and move in the upper end of thecolumn K. From the cross-head N extends laterally a trunnion or arbor Q,which projects through a slot is in the column K. The cross-head N ishollow and is split as indicated at n by a slot extending longitudinallyin one wall thereof. The spring M rests upon a perforated diaphragm inthe cross-head N and tends to force said cross-head upward. There is ahole having converging walls, which are screw-threaded, in the upper endof the cross-head N.

P is a plug having screw-threaded fins p on its shank which fit into thehole in the upper end of the cross-head N and when screwed up tend toexpand said cross-head and cause it to bind in the bore of the column K,while leaving an opening or openlngs between said fins to the outer air.The plug P is provided with a broad head which extends over the openingsfrom the column K.

Upon the arbor or trunnion Q is pivoted a pulley R, and around thispasses a belt S to the pulley T on the main shaft U of the engine.

V, V are fan blades upon the same shaft with the pulley R.

Oil is supplied to the crank case B through the column K, the plug Pbeing removed to afford an opening into which the oil may, be poured.The spring M acts to put the \required tension on the belt S and whenthe plug P is restored to position the cross-head N is caused to bind inthe column K with the required tension on the belt S. The fins 22 leaveopenings between them so that there is never any pressure in the crankcase to force out the oil through the joints as the air may move freelyout and in through the column K.

The action of the fan blades V, and the effect of the motion of thevehicle, is to force air through the apertures 9 into the casing G andhere it is heated by the heat from the engine imparted to the wall ofsaid casing by conduction and to the springs H and stems I by radiation.The heated air is drawn from the casing G through the pipe F through thecarbureter E where,

because of its high temperature, it readily takes up the gasolene vapor,then through t e the inlets of the engine.

Having thus described my invention what I claim is:

1. In a gas en 'ne, a crank case, a hollow column rising rom said crankcase and open at its upper end to the outer air and opening into saidcrank case, a cross-head in said column, and a fan carried by saidcross-head, said cross-head being so con structed as to permit air topass by it, substantially as and 'for the'purpose described.

2. In a gas'engine, a crank case, a hollow column rising from said crankcase and open at its upper end to the outer-air and toward its lower endto said crank case, a cross-head in said column, a fan carried by saidcross-head, a pulley carried by said cross-head and adapted to drivesaid fan, a second pulley and a belt passing around said pulleys, aspring acting against said cross-head to tighten said belt, and meansfor setting said cross-head in an adjusted position.

In a gas engine, a crank case, a hollow column rising from said crankcase and open at its upper end to the outer air and at its lower end tothe crank case, a crosshead in said column, a fan carried by saidcross-head, a spring acting against said cross-head, said cross-headhaving its walls slotted and being provided with a screwthreaded conicalhole at its upper ends, and a screw-threaded plug adapted to haveitspipe D to the branching pipe C and to as and for the purposedescribed.

4, In a gas engine, a crank case, a hollow column rising from said crankcase and open at its upper end to the outer air and at its lower end .tothe crank case, a cross-head in said column, a fan carried by saidcrosshead, a spring acting against said crosshead, said cross-headhaving its walls slotted and being provided with a screw-threadedconical hole at its upper ends, and a screw-threaded plug adapted tohave its threads engage in saidhole, and cover the opening to saidcolumn, substantially as and for the purpose described.

In a gas engine, a crank case, a hollow column rising from said crankcase adapted to carry the cooling fan, said column being open to theouter air toward the top and opening into said crank case toward itslower end.

6. In a gas engine, a column, a cross-head supported by said column andadjustable longitudinally thereof, a fan and pulley carried by saidcross-head, a second pulley, a belt passing around said pulleys, aspring acting against said first mentioned pulley to tighten saidbelt,.and means for securing said cross-head in the position that ittakes due to the action of said spring and belt.

In testimony whereof, I sign this specification in the presence of twowitnesses.

. CHARLES B. KING.
